Abstract

© 2015, Pakistan Agricultural Scientists Forum. All rights reserved. Higher levels of NO<inf>2</inf> are a danger to human health especially for children. A seven day study was carried to find out the ambient concentrations of NO<inf>2</inf> in 27 schools of Lahore with the help of passive samplers. In each school three sites were selected, viz: laboratory, corridor and outdoors. After 7 days exposure the tubes were subjected to spectrophotometric analysis. Results showed that the maximum values measured in laboratory, outdoor and corridors were 376μg/m<sup>3</sup>, 222μg/m<sup>3</sup> and 77μg/m<sup>3</sup>. Minimum values for laboratory, outdoor and corridors were 10μg/m<sup>3</sup>, 20μg/m<sup>3</sup> and 8μg/m<sup>3</sup>. Factors affecting these values were laboratory activities and proximity to main roads. These values were significantly higher than the standard values defined by EPA. Therefore children in schools were at risk of developing health complications.
